Cloud Security is currently top of mind for IT. In this blog post, I will provide a 10 point checklist to help you secure your OpenStack Neutron networking service. Ensure that you use “Defense in depth” as the primary security strategy and deploy a series of defensive mechanisms, as no single method exists for successfully protecting your entire service. This strategy ensures that even if one mechanism is compromised, another will be there to defend against the attack. Design network security in layers. So, instead of creating a single layer of network security protection at the perimeter, apply network security to every layer of the network, every component of the networking service and the communication channel.
